Harvard researchers estimate that cell phones contribute to about one in 20 U.S. car crashes, causing about $43 billion damage every year. Coincidentally, the convenience afforded by cell phones has been valued by users at that same amount. While the monetary values and crash statistics are little more than extrapolation, (sample quote: In addition to property damage, people were asked "what [they] would be willing to pay to avoid pain, suffering, and death"), the scary part is that approximately 2,600 people die each year from drivers with cell phones. Let's hope that policymakers considering a ban don't think the two sides are quite so equal.
